The Lewis structure of N3- (azide ion) is composed of three nitrogen atoms (N). There are 2 double bonds between each nitrogen atom (N). There are two lone electrons on each of the two outer nitrogen atoms. The
It is possible to draw a structure with a double bond between a boron atom and a fluorine atom in BF3, satisfying the octet rule, but experimental evidence indicates the bond lengths are closer to that expected for B–F single bonds. This suggests the best Lewis structure has three B–F ...
A drawn structure with a double bond on its own does not completely represent the structure of a given molecule There can be more than one possible structure for the same molecule! The actual structure is the average of all of the resonance structures Why resonance? Resonance spreads the charge...
Ethylene (ethene), CH2CH2, is the simplest molecule containing a carbon-carbon double bond. It is a gaseous plant hormone that plays pleotropic roles in plant growth, plant development, fruit ripening, stress responses, and pathogen defenses[1]. The Lewis structure of Ethylene The Lewis structur...

based on this Lewis structure. Nitrogen normally has five valence electrons. In Figure 1, it has two lone pair electrons and it participates in two bonds (a double bond) with oxygen. This results in nitrogen having a formal charge of +1. Oxygen normally has six valence electrons. In ...
New metal‐only Lewis pairs (MOLPs: Ru→Cr and Os→Cr) are prepared by the insertion of a zerovalent ruthenium or osmium complex into chromium–boron double bonds of borylene complexes. The reaction creates new borylene complexes (the first ever for osmium), and is crystallization‐controlled;...
